单点源模拟多点源诱偏仿真试验方法的研究

Research on the Decoy Simulation Test by Single-Source Instead of Multi-Source in RFSS

抗诱偏能力是反辐射导弹重要的评估指标之一,分析了辐射式仿真系统内开展诱偏试验过程和特点以及利用单点源开展多点源诱偏闭环仿真试验的可行性及实现方法。以空间分离点为依据,分时、分阶段计算雷达、诱饵站合成场在导弹处的法线,在辐射式仿真系统中利用转台中心、单点源间的固定方向进行等效,将其与导弹姿态的相对角度关系转换为转台转动指令角度,进而实现这种实际相对关系的等效构建,为辐射式仿真试验系统内利用单点源模拟多点源开展诱偏仿真试验提供一种思路。

The anti-decoy capability is an important evaluation index of ARM.This paper analyzes process and character of the decoy simulation test in RFSS,and the feasibility by single source instead of multi-source is researched and implementation method is provided.Based on the critical point concept,the normal of compound electric field at the passive Radar Seeker of ARM is calculated in different stage.In RFSS the fixed direction between turntable center and single source is equivalent as the normal.The angle relative to missile coordinate is transformed to the turntable instruction parameters,so the real angle relation is built up.
